[MND] Cognition & Perception Flashcards
What is the requirement for attention?
‘Arousal’
Attention is
Selecting and focusing on relevant incoming stimuli in the environment
What are the 2 types of attention?
1) Spatial Attention
2) Attention in Action & Behaviour
Spatial attention is dominant in the ______ hemisphere
right
Where in the brain mainly is ‘spatial representation and processing spatial information’?
Right parietal lobe
In terms of severity, spatial attention deficits can range from
Mild inattention (reduced attention sometimes, i.e. in complex situations) to neglect (never responds to stimuli on affected side/environment)
What are the theories of unilateral neglect?
1) Attentional system is out of balance (unaffected cortex over-rides the affected cortex)
2) Person may lose representation of the left space (person no longer has knowledge it exists)
Define unilateral neglect
Patients fails to attend or respond to meaningful stimuli on the affected side of the body or environment that side. This failure cannot be explained by sensory or motor deficits.
Motor neglect is an observed behaviour and is when
The person doesn’t spontaneously use the affected limb in bi-manual tasks and can’t be explained by sensory or motor deficits
Extinction is an observed behaviour when testing people who have neglect. This refers to:
A person identifying stimuli presented on each side separately.
When provided stimuli on both sides simultaneously fails to attend to stimulus on affected side
A person may show varying degrees of unilateral neglect ranging from
mild inattention to neglect
The Catherine Bergego Scale is a
Functional test to assess inattention/unilateral neglect
What are three simple tests to assess inattention/neglect?
1) Star Cancellation Test
2) Figure & Shape Copying Tests
3) Drawing Tests (i.e. drawing a clock)
Briefly, what are the 7 ways to treat spatial inattention/neglect?
1) modify environment
2) visual scanning training
3) eye patching
4) trunk rotation
5) limb activation
6) task related training
7) mirror therapy
Attention in action and behaviour refers to
Staying on task despite distractions
